SPECIFICATION forming part of Letters Patent N 0. 702,884, dated June17, 1902.

Application filed October 19, 1900. Serial No- 33,610. (No model.) I

To all whom it many concern.- I

Be it known that I, WILLIAM H. PENCE, a citizen of the United States,residing at Fairfield, in the county of Jefferson and State of Iowa,have invented a new and useful Improvement in lVood-Saws, of which thefollowing is a specification.

My invention relates to circular crosscutsaws for cutting wood intoshort pieces from poles or cord-wood; and it consists of certainpeculiarities of construction and combination of parts hereinafterdescribed, and particularly set forth in the claims.

In the drawings, Figure 1 is the perspective;

Fig. 2 is a sectional elevation drawn cross-v wise through the workingparts of the sawframe. Fig. 3 is a sectional elevation drawn lengthwisethrough the saw-frame and showing the saw withdrawn from cutting. Fig. 4

rocking frame B is rigidly secured, as particularly shown in Fig. 2. Oneend of the shaft F projects out beyond the saw-frame and is bent so asto stand below the inward portion of the shaft, but on a line parallelwith it. The idler O is mounted upon this depressed end of the shaft F,so as to main tain an even tension of the belt'T, as will be hereinafterexplained.

H is a bail or handle secured to the upper end of the rocking frame Band running clear across from one side to the other above the mandrel O,by means of which the operator may push the saw forward to cut the woodand also draw it back again for another operation.

On a rear sill of the saw-frame is attached a bracket provided with apivot I, and to this a foot-lever J is secured. Another bracket or arm Lis attached to a cross-bar U of the rocking frame 13, and the end ofthis arm or bracket is connected to the inner end of the foot-lever bymeans of the connecting-bar K. By pressing on the outer end of thefoot-lever J the rocking frame B will be thrown forward,

ward.

thus assisting the hand or acting independent of it in forcing the sawinto the wood. It will be seen that the foot-lever J is connected to therocking frame B, so that its 0perative movement will be contrary to thatof the rocking frame B, to which the hand-bail H is attached, and bythis means the power that is expended on the one will have a tendency toreact on the other, thus adding greatly to the ease of operating thesaw.

On an upper cross-bar Va coiled spring M is attached, and to the freeend of this spring a rod or chain N is secured, and the free end of thechain is secured to a suitable part of the saw-frame. The length of thechain N is adjusted so that when the rocking frame B moves forward pastthe center the spring M will begin to tighten and to exert its power onthe frame 13 as it continues to move fortVhen the pressure of the handis removedfrom the bail H or the foot from the lever J, or both, thespring will draw the frame B back to the center, when it will of its ownmomentum move back to its original position, as shown in Fig. 3: By thismeans the foot is made to assist the hand in pushing thesaw forward andthe spring to assist the hand in drawing the saw back, or the hand maynot be used at all, and the foot and the spring will control themovement of the saw, as desired.

P is a balance-wheel which may be used to maintain the momentum of thesaw in the usual manner.

Q is an inclosed hood having parallel sides and one open end. This hoodis secured to the saw-frame by hooks X or other removable 'fasteningsand is used to protect the operator from the saw, as well as to protectthe saw and to act as abearing for the wood being cut.

R is the saw-table,which is provided with shoulders \V to limit themovement of the rocking frame 13, and S represents the stick of wood tobe cut.

T is the belt which drives the saw. It passes over the idlers O and Dand around the sawmandrel pulley E. As the frame B moves forward, theidler 0 being mounted on the end of the shaftF below the pivot of theframe B it will be thrown back a little, and when the frame is drawnback the idler C will be thrown forward a little. By this means thetension on the belt T will always be the same and will not be madealternately tight and slack, as it would be were the idler C and theframe B pivoted upon the same line.

It is apparent that variations may be made in the details ofconstruction without departing from the spirit of my invention.Therefore I do not confine myself to the exact construction shown; but

\Vhat I claim as new, and desire to secure by Letters Patent, is-

1. In Wood-saws, the combination of a main frame, arocking frame hingedat its lower end to said main frame, and at its upper end carrying asaw-mandrel, a hand-bail secured to the upper end of the rocking frameand passing across from one side to the other above said mandrel, and afoot-lever to assist in moving said rocking frame; the connection ofsaid hand-bail and foot-lever being such that the operative movement ofthe one will be contrary to that of the other, whereby the reaction ofthe power to operate the one will assist in operating the other.

2. In wood-saws, the combination of a main frame, a rocking framepivoted at its lower end to said main frame and having a handbail at itsupper end and a cross-bar near its lower end, a horizontally-projectingarm secured to said cross-bar a foot-lever pivoted to the lower end ofthe main frame and a bar pivotally connecting together the free end ofthe arm and the inner end of the foot-lever, the operative movements ofthe hand-bail and foot-leverbein g contrary to each other,whereby thereaction of the power to operate the one will assist in operating theother,substantially as described.

3. In wood-saws, the combination of a main frame a rocking frame hingedat its lower end to said main frame, and having a hand-bail at its upperend to give it movement in both directions, a foot-lever secured to saidrocking frame to give it movement in one direction and a spring to giveit movement in the other direction, the spring being adapted to assistthe return movement of the hand-bail, and the reaction of the powerapplied to the footlever to assist the forward movement of said bail,substantially as described.

4:. The combination of a main frame,a rocking frame pivoted at its lowerend to said main frame and having a cross-bar near its lower end, ahorizontally-projecting arm secured to said cross-bar, a foot-leverpivoted to the lower part of the main frame, and a connecting-bar,hinged at one end to the inner end of said foot-lever, and at the otherend to the end of said arm, substantially as described.
